Brake cooling ducts without removing things?



  Ph2 Clio 172
Is it possible to get any meaningful cooling to the front brakes from the fog light surrounds using pipe work without having to remove the carbon canister and the acoustic valve?

I tried and failed. Arch liners, one of the horns, and carbon can now gone.

In essence hanging under the bumper, maybe if a splitter was fitted then cut into that.
See my above post, edit got timed out lol.

I've got a splitter.

So I assume there isn't room to run a pipe from the fog light housing to the inside of the arch without removing things?

I had a nosey under the passenger side the other day while fitting my dogbone and there looked to be plenty of room to feed a pipe from the fog surround to the inside of the arch. At most you would have to move a horn. It would be far from a straight line, but with the air being forced in it wouldn't matter.

Completely forgot to check the driver side though (doh!) and that's where the carbon canister is isn't it? So I assume that side would be harder?

No chance on drivers side without removing or possibly re positioning it. Mines removed.

Passenger side it's possible to re position the horn, I made a new bracket for it. Can't remember where the acoustic valve sat.

Just remove arch liners.
There is a splitter that I have seen on a Clio, with bit's that could be cut out and a oblong scoop put in.

Well decided to have a bosh today and see what I found. Turns out it should be fine without removing anything. You can bend the horn out the way on the passenger side, and if you undo the big bolt holding the carbon canister you can then bend that a little out the way on the drivers side. Should be fine to fit ~100mm ducting from the fog to the inside of the arch liner.

Any idea where to buy 100mm CAF ducting?

Whats the right term to search for? I'm not getting anything on eBay searching for 'caf' and if I search for 'ducting' I'm getting tumble dryer pipes :)

I have thought of this, like done on the R35 GTR so must work quite well. Do you think the small scoop area and more importantly less dirrect (straight route to the calliper would make for insufficient cooling?
 
You could use aluminium sheeting to make a horizontal air deflector riveted onto the wishbone, this will pick up air up to a second are deflector (sounds complicated but looks simple). I have seen this on a race prepped Clio. Likewise having air coming through the fog light housing and hitting a vertical deflector works well |( like most of us on here have used and slimier to the Cup Racer air deflectors

We still have half a horn and a carbon canister, haven't got round to removing it. We grew properly desperate on the brake cooling front, maybe it's just us not being arsed to change fluid every 6 months. Resulted in this monstrosity, ducts feed into wheels. Yet to be tested on track

A gentle blower suggests it gets air on there from pretty horrendous angles. But things work differently when blowing air instead of driving into static air so we will see.

Looks like a little lobster now! Shows you can fit ducts with the bits still in there though
